Just a quick note to those Nexus 4 owners and developers out there looking for a quick and reliable way to download the official factory image: Google has put it back online. While the image has been readily available in the community during its unexplained absence, it's nice to see that whatever issue prevented Google from posting it has presumably been resolved.

The Android version and build numbers remain unchanged, as do the checksums, so it appears this is the same file that was posted originally.
